The rules are the same as the 100-tier, after getting a hit, the probability of the corresponding technology level drops, down to the next level.
The only slightly good news is that it only drops 10% probability, much better than the previous two tiers.
Gu Hang drew twice more.
Luck was good once and bad another, getting him a basic and an elite level.
The basic level was particularly bad, yielding a Resource Detection Technology Blueprint.
Unlike the technologies obtained previously, this included not only the production of finished Black Boxes and mainframe Black Boxes, but also an extra item: a full set of detection knowledge encyclopedias and tutorials.
The latter was quite impressive.
Gu Hang immediately thought that with these, he could form several resource detection teams to explore what valuable resources lay within the lands under his control.
